LG	21FJ6RB	It does not tune channels and tsound is no image on the TV when you connect the antenna or connect the cable. The AV shows vertical lines.	R 512 of 4.7k	Replace	Mauro Mascarenha Tel.( 88 )981422821 Parazinho - Ceara
LG	RP-20CC25 MC 059A	Does not tune channels and does not accept av when connecting the antenna or connecting the cable the av shows vertical lines.	R 512 of 4.7k	Replace	Mauro Mascarenha Tel.( 88 )981422821 Parazinho - Ceara
LG	RAD226B	Does not turn on, does not light up or standby without 3.7v	Dz901 with leak	Replace 27v dz901 with leak	beto2828
LG	47LV5500	LED stand by turns on white, no sound dark image	I checked the power supply, the normal voltages 12v, 24v, 3.5v, the display LEDs don't light up, I checked the t-con board, 12v is missing, this 12v comes from the main board, measure all the voltages that feed the micro 3.3v 5v 2 .5v 1.5v are normal micro faulty lge35230, I changed this bga the tv worked and 12v appeared on the t-con led they lit up	TV was in test defect resolved	Andre
LG	RP 20CC25	STBY LED on normal power supplys but does not fire	Crystal with one of the pins broken	Cristal cm dft	Raimundo
LG	32LJ600B	Doesn't start	Wireless card defect. When I plugged the TV in, it started working normally again.	Replace wireless card	Thiago Silva
LG	32LS3400	When the power supply is cold it has 3.5v from standby if you unplug it the voltage disappears then you just have to wait a while for it to start working again	Q502 transistor smd ktn2222as		Mega Center
LG	CM7420	No sound comes out	The three resistors in series of 680k, 680k, 330k that feed the oscillator circuit of the 50 volt power supply		Edezio eletronica
LG	RP29CC90	Horizontal deficiency lacks width	Change the coil l401		eletrônica renovação Maranhão
LG	21FU1RL	Vertical closed	All components in the vertical sector, deflector coil and vertical outlet were tested, but nothing was found. checking the micro pins does everything, and on pin 16, tsound is a capacitor c512 / 0.47 pf, this capacitor was open.	Capacitor replaced c512 / 0.47 pf	Carlos Alberto (ELETRÔNICA BATURITÉ)
LG	21FU1RL	Vertical closed	All components in the vertical sector, deflector coil and vertical outlet were tested, but nothing was found.		Carlos Alberto (ELETRÔNICA BATURITÉ)
LG	42CS460	TV turns on, but tsound is no sound or image, the backlight is on. It works with keyboard and control commands.	2.5v regulator near nvram, tsound was no voltage output. Tsound was no short in the line.	Replace	joaomvjr
LG	50PJ350	As soon as I turned on the TV, the power supply sent the voltages vs, va, m5v which goes to the ysus board but in a matter of seconds this power supply dropped.	The 22r 5w resistor r929 open	I made the replace and the problem was solved	Eliezer
LG	42PJ250	Turns on, then turns off immediately, then doesn't turn on. You have to unplug it and turn it on and off again.	Check the line of resistors 113 to 118, possible poor contact.	Resolder all resistors on this line.	arock
LG	42LM7600 LB22E	Does not turn on, no standby, when pressing power the LED flashes twice but the TV does not turn on	+24v shorted on the main board connector but in fact it is the +24v_amp that is shorted on the main board	C5422 in a cracked short due to so much heat, I replaced it with a 104z ceramic and the power supply started to turn on normally	2000
LG	32LD460	Sometimes it works for a while and turns off	Low pfc circuit. normal voltage between 385v and 390 was 230v	1.8m resistor mesh. remove, clean, and install other	DEBIQUE
LG	20CB67	Vertical strip at the top	Those who have already done everything couldn't solve it, just change the resistor r301 from 15k to 13k		eugenio barreto
LG	14FK3RB	Vertical closed	27k r311 open after replacing it worked perfectly		Protec eletronica
LG	32LS3400	Turns on without image, when pressing standby it turns off but no image appears, short killing the 24v and 12v power supply. It looks like a power supply but it isn't.	Shorted smd capacitor 524 or 523 near the 4 coils next to each other on the main board.	Replace c523 or 524 on the main board	jeanprede
